Claims

[Scope of utility model registration request]

A headstock for attaching a spindle that fixes the workpiece to the tip, and a spindle for attaching a rotary tool.The toolstand is placed on the base in a relatively perpendicularly slidable state, and the headstock and toolstand are A reducer and a servo motor are connected to each of these through means for converting rotational motion into linear motion in order to slide the workpiece, and a main shaft is mounted on the headstock and has the workpiece attached thereto. In a numerically controlled machine tool having a speed reducer and a servo motor for rotation, the speed reducer for sliding the headstock and tool rest has a cam surface on the outer periphery and is driven to rotate at a predetermined rotational speed. a turret that is fitted on the input shaft and the output shaft so as to be integrally rotatable and has a plurality of rolling cam followers protruding from the periphery at equal intervals to engage with the cam surface; The main shaft is formed in a shape that converts the rotation of the input shaft into rotation of the turret and the output shaft at a constant reduction ratio by sequentially engaging the plurality of cam followers with the cam surface when the input shaft rotates. The speed reducer for rotating the gear includes an input shaft having a cam surface on the outer periphery and driven to rotate at a predetermined rotational speed, and a turnlet having a plurality of rolling cam followers protruding from the periphery at equal intervals. An intermediate shaft having a cam surface and a turret on the same axis is provided between the output shaft which is rotatably fitted on the output shaft, and the turret on the intermediate shaft connects the cam surface on the input shaft with the intermediate shaft. A machine tool characterized in that the cam surface engages with the turret on the output shaft and has a two-stage reduction gear for rotating the main shaft.
